Bank card 4-factor verification is a secure authentication method that confirms identity authenticity and information consistency by cross-checking four key pieces of information: the cardholder's name, bank card number, ID number, and bank-registered phone number.
What are the common reasons for a failed 4-factor verification?
The entered information does not match the bank's records (e.g., incorrect name, ID number, or registered phone number); the bank card has been reported lost or frozen; or there is a temporary system failure.
Why does it say "Phone number mismatch" when the number is correct?
You must ensure that the entered number is the bank-registered phone number (the one registered when opening the account), not necessarily the one currently in use. You can check your registered number at a bank counter or via the bank's official app.
The ID number must be an exact 18-digit match, and the bank card number must be entered completely and accurately. Verification results are for reference only; please rely on official bank confirmations for critical business decisions. Ensure your network environment is secure when transmitting sensitive information.
Financial-grade data encryption ensures information security during transmission. It is recommended to set request rate limits when integrating the API. Typical example: Entering "Zhang San_110101199001011234_6225880212345678_13800138000" returns "Bank of China_Debit Card_Matched".
